Oil & Gas production systems

Produce more from your field
Operational strategy optimization requires addressing several questions simultaneously: which wells to operate, choke back, or apply gas lift; how to manage the production–facilities interaction; how to meet processing constraints. Model-based optimization helps operators maximize production while reducing operating costs.

Presented under the SPE Expert Hour Series.

Production optimisation and integrated asset optimisation
When the field is modelled mathematically, normally only the production system (sand-face to separator inlet) is considered in the model. Increased production and a much better understanding of the asset can be achieved by including the facilities components in the model. To model the integrated production and facilities systems, software tools can be linked at the system boundary (usually the separator) and data (pressure, flowrates, etc.) passed across this boundary. This approach not only leads to model inaccuracies (e.g. different fluid definitions) but also prevents true asset optimisation as only the individual elements can be optimised. To gain the maximum benefit from an integrated model, the same software tool should be used for both the production and facilities elements.

Production optimisation for Oil & Gas fields
This webinar will explain the technical basis of production optimisation and its practical application. In today's low price environment, oil and gas field production optimisation is of paramount importance to all operating companies. Each field must maximise production while keeping CAPEX and OPEX to a minimum. The interplay of decisions on routing, well on/off and artificial lift is too complex for any person to find the optimum or even a point close to the optimum. Advanced software dedicated to field optimisation can use global optimisation techniques to identify significantly better daily production values than existing solutions.

Integrated asset optimisation
This webinar describes a new approach to integrated asset optimisation. This approach incorporates the interaction between the production system, the fluid properties and the process equipment, which can only be fully described by a complex facilities model integrated with the production model. gPROMS ProcessBuilder combines state of the art optimisation technology with a library of standard process unit operations including separators and compressor trains. The gPROMS Oilfield library includes extensions to address challenges specific to oil and gas production optimisation including the translation of black oil models to fully compositional equation of state models.

Relief, flare and blowdown centre of expertise

Fire depressurisation analysis in oil & gas facilities
The aim of depressuring in a fire emergency situation is to prevent possible catastrophic escalation. This is achieved by routing hydrocarbons into the flare network. The effect is not only to remove the flammable inventory from the system but also to reduce stresses in pipes and vessels. This webinar discusses changes in the 6th edition of API 521 on fire analysis. The presentation will introduce the analytical methodology for fire analysis; then examine the impact through case studies.

Lessons from incidents: placing best practice analysis at the heart of process safety management
Several major incidents involving flare and relief systems can be traced to a failure to recognise hazards and perform adequate analysis. This webinar uses the incidents as examples to explain how industry guidance such as API 521 and good engineering practices have been enhanced to prevent future accidents and promote inherently safe design. It will describe the best practice solutions you need to effectively manage process safety.

Fire depressurisation in Oil & Gas facilities: detailed analysis
This webinar follows on our previous, Part 1, webinar on the topic. The presentation will briefly review the topics introduced in Part 1 focusing on the analytical methodology for fire depressurisation analysis and then discuss through case studies: the conventional workflows and how these can be improved in terms of efficiency, consistency and reduced uncertainty through the use of dynamic flare analysis and optimisation.

Accurate low temperature analysis for blowdown systems under API 521
In conventional screening methods, calculations of safe design temperatures are based on analysis of a single pseudo-vessel with simplified representations of thermodynamics and heat transfer. Such methods are no longer seen as providing either the necessary assurance for safe operation or the required information for making capital expenditure decisions. In this presentation we discuss a rigorous approach, using distributed blowdown system models, to assess risks of cold temperature brittle fracture during process depressurization. We highlight the important benefits of this approach and when it should be applied, and discuss how it fits into existing engineering workflows and how it is aligned with the changing industry guidelines.

Fire analysis in upstream Oil & Gas facilities
The aim of depressuring in a fire emergency situation is to prevent possible catastrophic escalation. This is achieved by routing hydrocarbons into the flare network. The effect is not only to remove the flammable inventory from the system but also to reduce stresses in pipes and vessels. This webinar will discuss changes in the 6th edition of API 521 on fire analysis. The presentation will introduce the analytical methodology for fire analysis and explain the limitations of the empirical approach considering equipment in a well-ventilated fire area.

Optimal selection of materials of construction for gas processing facilities
In gas processing facilities, minimum metal temperature usually sets the materials of construction. If metal temperatures below -46°C are predicted, Low Temperature Carbon Steel presents an embrittlement risk and designers must switch to expensive stainless steel construction. Such decisions have a huge impact on project costs, order times and project viability. In this webinar, we will present a case in which the decision was worth more than $1,000,000,000 in CAPEX.

Assessing the design temperature of flare headers
(contact PSE for access)
In many Oil & Gas facilities, the blowdown operation sets the minimum metal temperature and therefore drives materials-of-construction decisions. The choice between stainless steel and low temperature carbon steel can be worth many millions of dollars in material costs. A poor choice can compromise asset integrity. As industry guidelines evolve to highlight the importance of accurate low temperature assessment, best practice increasingly demands rigorous modelling techniques. This webinar will demonstrate an advanced process modelling approach to accurately assess the design temperature of flare headers.

Accurately assess flare system capacity using dynamic analysis
(contact PSE for access)
Traditional flare modelling assumes that the header and knockout drum are at steady-state conditions. A more rigorous, fully dynamic flare model can be used to produce more efficient designs, or to demonstrate the sufficiency of existing systems. In this webinar, with reference to case studies, we show how the transient behaviour of the flare system can be accurately predicted for blowdown events, avoiding unnecessary modifications and saving tens of millions of dollars in capital expense.

Advanced Modelling of Relief Systems
(contact PSE for access)
An emergency pressure relief incident is over in minutes. Do you really know what happens during that critical time? How much capacity can your flare network REALLY handle? Do extreme cold transient temperatures place your system's integrity at risk, and if so, for how long? This webinar demonstrates our validated approach to answering these questions using gFLARE® technology.

Compression train optimisation using Advanced Process Modelling
This webinar describes an approach to rapidly determine the optimal design parameters of a compression train using rigorous model-based optimisation methods. The approach makes it possible to accurately determine trade-offs between capital expenditure and operating costs.
